Overview

Our marine engines for auxiliary applications give you low cost of ownership, excellent fuel economy and competitive prices both for engine and parts. Auxiliary engines generate a vessel's on-board electricity, so they need to be quick to start and feature low noise and low emissions. For heavy duty requirements, such as powering a large fishing vessel's electrically driven net haul system, you really need the extra power that a dedicated auxiliary engine will give to you – rather than generating electricity from the propulsion engine.
